This invention relatesto'a churn and a device for attaching the churn to a washing machine.

The churning of butter is frequently done at the dwelling house, usually by continuous rotation of the churn in one direction with paddles in the container for the. cream to provide the desired agitating action. Many dwellings atl the present time haveT electric power and electric machinery `forutilizing theelectric energy supplied. Among such machinery, a washingmachine isffrequently used, to which attachments maybe applied vfor/accomplishing .other objects than the-washing of clothes. Thewashing ma.- chine agitator hasan oscillatory motion through substantiallyl 180 degrees-in onefdirection and then backthroughlodegrees inv the other direction. The utilizationyorthis oscillatory lmotion for the -churning-of butter 'instead of continuous rotation in one direction presents several difficulties, especially with a circular container for the cream equipped with paddles, and the movementv of the container on'A ther agitating vanesofgthe washing machine. Also, in the use of a churnwithpaddles'itis dilicult'to clean the equipment.

One of theobjects of vthis'invention is to provide au simple andinexpensive churnzwhich'mayl be mechanically operated by attachment' toV aV washing machine.

Another object ofthe inventionxisfto eliminate the necessity ofthe useof-paddles in the cream container for churningA butter.

Anotherfobiect of theinventiongisito provide a mounting for the cream containerwhich mayl serve to attach it to the agitator-of many differ.- ent makes of WashingA machines now Ion the market.V

Another object ofthe inventionisto'provide for thel simpleand easy positioning Vand removal ofthe churn on thevanesfof Vthe* washing machine so that it may be retained in position. by'` its own' Weight.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In proceeding with this invention, I provide some out-of-round container so that its oscillatory movement will disturb the contents within rather than merely slipping about the liquid con tents with a minimum agitation; and I thus utilize the oscillatory motion given to the liquid container. By shaping this container substantially in the pattern of an oval, the disturbance provided is of such extent that no paddles in the cream are required for agitation. The oval also permits of easy cleaning, and thus a very simplified form of device is present by this shaping of the churn. This shaping also permits of ay engage the agitator of a washing machine so that it may be set thereon and be held by its own weight; and thus the oscillatory motion of the agitator of the washing machine will be imparted to the framework and through the framework to the ch-urn for the agitating of the cream therein; and the following is a more detailed description ofv the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished. f

With reference to the drawings, l@ designates. the outer'casing of a Washing machine having` a bowl-portion H throughthe bottom of which there extends'shaft i2 which carries a bell-likeV `agitator I3, hollow as at l5 and having a pluperiphery of the bell and merge into a hub |'o` which is standard equipment of one type of washing machine, while other makes have similar or different agitators with vanes for performing the function of washing clothes and to which my invention is adaptable.

The churn or cream container is designated generally 2|] and is shown in perspective in Fig. 8, while it is shown in section in Figs. 1, 2, and 5. 'Ihe general form of this container is tubular having a side wall 2| with a smooth inner surface 22. The tube, however, is not of uniform shape throughout its length, but rather is elliptical at its lower portion 23 and cylindrical at its upper portion 24, one shape merging into the other as may best be seen in Figs. 2 and 8. An elliptical bottom wall 25 is provided with a` down-turned flange 2B which is soldered as at 21 to the side wall 2|. Suitable openings 28 are provided through the flange 2B and lower edge of the bottom wall providing a reinforced portion for mounting of the churn, as later will be more fully described.

A cover 29 having a handle 30 and flange 3| may telescope into the top of the churn and be lifted therefrom for access to the contents of the churn. The usual pouring spout (not shown) will be provided in the cover. Handles 32 are provided at diametrically opposite points near the top of the churn for lifting or carrying the churn from one place to another.

The oval arrangement of the bottom portion of the churn when oscillated causes a violent agitation or excitement of the liquid contents of the churn which is suicient to perform the butter-making action without the use of a paddle.

In order to mount this container or churn 20 on the agitator I3, I have provided a framework designated generally 35 and shown alone in Figs. 6 and '7. This framework is designed primarily for the convenient mounting of legs for attach ment to the churn and the supporting of the churn on the agitator. One convenient formation of the frame is by means of a plate 36 with a down-turned ange 37, forming an upper portion of the frame. This plate will be of a size and shape to fit the recess 38 of the bottom portion of the churn and is a convenient mounting for brackets 39 on which the legs 40 are hinged. The lower portion of the frame consists of an annular member 4| which provides for holding the legs in the desired position of adjustment. This annular member 4| is attached to the upper plate 35 by struts 42 secured at intervals, and here shown as three in number, for spacing these two parts 36 and 4|, as seen in Fig. 6.

The legs which form the primary holding and supporting function are positioned in this frame- 4 work to have considerable freedom of movement, and each consists of a channel or U-shape in cross section, perhaps best seen as to their crosssectional shape in Fig. 3. Each leg is pivotally mounted in a bracket 39 by means of a bolt 43 and nut 44 (see Fig. 4) and is adapted to swing about the bolt 43 as a hinge axis. These legs are three in number and by reason of the location of the brackets are positioned equally angularly about the axial center of the frame. The lower portions 45 of these legs will engage between the vanes I4 and 46 and will be held from outward movement by reason of the links 4l which are clamped in adjusted position, as shown in Fig. l, to the annular member 4| by bolts 48 and wing nuts 49 which extend through an opening in the annulus 4| and through one selected opening 5U in the link 41. Thus, these legs may be swung inwardly cr outwardly about their hinge 43 to provide different spacings in the center and provide su'lcient adjustment so that many different agitators may be accommodated.

The frame is secured to the lower part of the churn by openings 5| in the flange 3l registering with openings 28 for the reception of bolts 52 (see Fig. 1) and wingsecuring nuts 53, whereby the framework is secured to the churn and becomes an assembled unit therewith. This assembled unit of churn and mounting frame may be lifted from the agitator of the washing machine and may rest upon any flat horizontal surface by reason of the annulus 4| being in substantially a single plane below the legs. Thus, this annulus serves as a rest for the churn when out of working position as well as a holder for the supporting legs when. in working position.
